获取两个日期之间的日期列表未正确返回JS [英] Getting list of dates between two dates not returning correctly JS

问题描述

我有一个开始日期和结束日期，我想生成这两个日期之间（包括）的日期列表。但我不知道为什么它不起作用...

I have a start date and an end date, and I want to generate a list of dates between (and including) these two dates. But I don't get why it isn't working...

我传入了几个JS日期对象，我已经显示了他们登录到控制台的内容下面

I pass in a couple of JS date objects, I've shown what they log to the console below

function dateList(dateStart, dateEnd) {
  console.log(dateStart);
  console.log(dateEnd);
  var dates = [];
  for ( i = dateStart; i <= dateEnd; i.setDate(i.getDate() + 1) ){
    dates.push(i);
  }
  return dates
}

推荐答案

尝试添加新日期（i），而不仅仅是 i ：

Try to add new Date(i), instead of just i:

function dateList(dateStart, dateEnd) {
  var dates = [];
  for (i = dateStart; i <= dateEnd; i.setDate(i.getDate() + 1)){
    dates.push(new Date(i));
  }
  return dates;
}

console.log(dateList(new Date('2017-05-08'), new Date('2017-05-12')));
